Patent CA-1024082-A (CA)
Title: Decantation lamellaire avec deflecteurs sur les lamelles
Inventor: RICHARD YVES
IPC: B01D21/01
Filed: 1973-08-21
Granted: 1978-01-10
Abstract: PRECIS DE LA DIVULGATION :           L'invention se rapporte à un procédé pour le traitement de liquides, notamment d'eaux, par décantation à lit de boue pulsé.  Le liquide à traiter est en contact avec le lit de boue et traverse ce dernier avec une vitesse ascensionnelle.  On confère au liquide à traiter, à son entrée dans l'appareil et lors de sa progression dans le lit de boue une direction d'écoulement inclinée sur l'horizontale.  L'inclinaison est telle que les boues  constituant le lit sont amenées à se déposer en donnant naissance à des courants préférentiels du liquide et des boues.  Les courants favorisent la tendance au tassement des boues.  Le procédé permet, suivant les cas, soit d'opérer sans modifier la vitesse ascensionnelle moyenne du liquide à traiter, avec un lit de  boues de forte concentration en matière de suspen-sion et donc d'obtenir une qualité d'eau traitée supérieure, soit d'augmenter sensiblement la vitesse ascensionnelle du liquide à traiter, sans obtention d'une qualité d'eau équivalente, soit de combiner ces deux possibilités.

Abstract: DOCTOR BLADE ASSEMBLY                Abstract of the Disclosure A doctor blade assembly for paper coaters and gravure rolls and other doctor blade applications includes a cantilever-support blade controlled by a tube-type actuator.          The tube has a collapsible wall section adjacent the blade and a blade-engaging extension which bears against the blade between its supported and free end.           In one embodiment, a transversely movable profile adjuster or series of profile adjusters are disclosed which selectively apply side forces to the wall section of the tube to permit corresponding selective pressure adjustments on the blade, for the purpose of reducing or eliminating localized coating non-uniformities.           A novel blade retention assembly permits the clamping of blades of varying thicknesses and includes one or more trans-versely positioned magnets for temporarily retaining the blade on the support.   An opposing clamp is formed with an elastomeric pad or expandable tube which engages the blade adjacent its inner edge and which forces or urges the blade downwardly against a machined seat to assure proper seating.           In a further embodiment, a twin blade coater is disclosed in which the tips of the blades are independently rotatable about a common axis and which utilize a pair of the tube-type actuators connected to a common pressure source.

Abstract: ABSTRACT OF THE DISCLOSURE                 This application describes a liner destined to form part of a tubular container useful in the packaging of dry and liquid products such as hydroscopic oil, food products, and liquid foods.  The liner of the tubular container may be composed of four adherent plies of polyester-polyolefin-metal foil-heat seal coating-which liner bonds through the heat seal coating to an outer portion of rigidity-imparting material. The composite structure constitutes the tubular wall for a container and is formed by winding elongate strips of its constituent plies onto a mandrel where they are bonded into an integral structure, for example, by heating.  The can or container itself may then be formed by cutting the resultant tubular structure into appropri-ate lengths and attaching end closure means thereto.

Abstract: Abstract of the Disclosure This invention relates to gun sight lighting device and more particularly to an attachment that can be affixed to a gun sight to enable the gun and the sight to be used in situations where very little incidental light is present. The attachment consists of a source of light that is attached to a gun sight of the type that operates on the principle of superimposing a sighting image on a target.  The light source is directed specifically at illuminating the object that is used to develop the sighting image so that the gun sight can be used in conditions where the level of incidental light present is insufficient to enable the sighting image to be readily seen by the user of the sight, but the level of incidental light is sufficient to permit the target to be seen by the user of the sight.

Abstract: Abstract of the Disclosure Apparatus is disclosed for the manufacture of sausages of the same length and the same weight in a common sausage casing.  It includes a filling pump for filling the sausage mix into a stuffing tube onto which the loose sausage casing is pulled, a braking and twisting device arranged on the free end of the stuffing tube for the holding back and twisting of the loose sausage casing with respect to the filled sausages, and a conveyor device arranged behind the twisting device for the further conveying and holding of the filled sausages against twisting.  The conveyor device acts on the filled sausages from the outside by a plurality of supporting members movable in the direction of conveyance and being adapted to be driven with adjustable speed.  The supporting members of the conveyor device transverse to the direction of conveyance form a uniform supporting surface which is maintained free of projections such as dividing members.  The twisting device is inter-mittently controllable as a function of the amount of sausage which has been introduced in the meantime.  Along the linear path of conveyance or removal of the sausage casing there is provided a cutting device for dividing a sausage chain at the twist constrictions, which device is actuatable syn-chronously with the twisting device and can be set at a distance from the twisting station which corresponds to or is a multiple of the selected length of sausage.

The clutch includes a clutch and a housing member rotatably disposed relative to one another. Each member has a shear surface.  The surfaces define there-between the operating chamber.  The storage chamber is located in the housing member and is in fluid communication with the operating chamber via a discharge passage and the inlet passage. Pump means in the operating chamber displace fluid through the discharge passage from the operating chamber to the storage chamber.  The inlet passage directs fluid from the storage to the operating chamber.  A movable valve arm selectively seals the inlet passage.  The valve arm is moved via a solenoid action in response to actuation of the magnetic field.  Fluid is disposed within the clutch and is used,when located in the operating chamber, to rotate the housing members in response to rotation of the clutch member.  When the fluid is displaced from the operating to the storage chamber, rotation of the housing member is reduced.
